I have been shielding my 6 years old son from electronics, except 40 minutes of TV twice a week. I have no idea how to grow his patience and perseverance, though. He is like me, who doesn't have a lot of patience to begin with, so I can't really guide him through some of the situations. We have been taking him to some activities as well as reading to him but nothing really sticks.
I just hope eventually he loves reading and learns in a more traditional way instead of from laptops and pads.
